Hi
I have a scatterplot of points with pch=1 and a single point with
pch=3, lwd=3.
It has a high line width to attract attention to it.
The following script
plot(rnorm(10),rnorm(10),col="black")
points(rnorm(10),rnorm(10),col="red")
points(0,0,pch=3,lwd=3)
if(TRUE){
legend("bottomleft",c("a","b","Truth"),pch=c(1,1,3),col=c
("black","red","black"))
} else {
legend("bottomleft",c("a","b","Truth"),pch=c(1,1,3),col=c
("black","red","black"),lwd=c(0,0,3))
}
doesn't quite work as desired: the third symbol in the legend is not
the right line width.
Replacing TRUE with FALSE doesn't work as desired either; the first two
symbols end up with a line I don't want.
The same happens with lwd=c(NA,NA,3).
How to coerce legend() into doing what I want?
